Abstract:

Here we report the solution−liquid−solid (SLS) synthesis of silicon (Si) nanowires. Nanowires are grown by trisilane (Si₃H₈) decomposition in a high boiling solvent, octacosane (C₂₈H₅₈) or squalane (C₃₀H₆₂), in the presence of either Au or Bi nanocrystals. To our knowledge, this is the first report of a colloidal synthetic route carried out in a solvent at atmospheric pressure that provides crystalline Si nanowires in large quantities.
